New Cross-Border U.S. Pipeline Proposal Could Revive Idle Keystone XL Assets: Analysts

Why It Matters

Reviving Keystone XL assets could unlock stranded capital and ease Canadian crude bottlenecks, while exposing the project to heightened political scrutiny.

Key Takeaways

• Bridger proposes 550,000 bpd cross‑border pipeline
• Likely ties into idle Keystone XL pipe in Alberta
• South Bow evaluating expansion using existing permits
• Canadian export routes near capacity, increasing demand
• Presidential permit approval faces political uncertainty

Pulse Analysis

The Keystone XL saga left more than a hundred kilometres of pipe buried in Alberta, a sunk‑cost asset that has attracted renewed interest as Canadian oil producers scramble for export capacity. While the original expansion was halted amid shifting U.S. administrations, the physical infrastructure remains a valuable conduit that could be repurposed with relatively modest investment. Industry analysts now see the dormant line as a logical feedstock for any new cross‑border conduit, offering a "head start" that could shave billions from capital expenditures.

Bridger Pipeline LLC’s filing outlines a 550,000‑barrel‑per‑day route that would divert crude southward to a storage and pipeline hub in Wyoming, diverging from Keystone’s original southeast trajectory toward Nebraska. By potentially linking to the existing Keystone pipe, Bridger could bypass the need for new right‑of‑way acquisition and extensive permitting, accelerating project timelines. South Bow’s tentative endorsement—focused on leveraging existing permits—signals that the company is willing to monetize its idle assets, a move that could reshape the economics of Canadian crude export and provide an alternative to the congested Trans Mountain and Enbridge Mainline corridors.

However, the proposal must still secure a presidential permit, a hurdle that has proven politically volatile. The permit was granted under the Trump administration, rescinded by President Biden, and could be contested again depending on future policy shifts. Moreover, the project will compete directly with Enbridge’s Mainline expansion, which aims to add up to 400,000 barrels per day by 2028. Investors and policymakers will be watching closely to see whether the revived Keystone assets can navigate regulatory risk and capture market share in a tightening North American oil transport landscape.
